WEATHER STRIP.

Application filed January 5, 1924:. Serial No. 684,499.

Toull 'whom t may concern.'

Be it known that we, DOMNICK Kernen and RICHARD 0.1 OAKLEY, citizens of? the United States, residing at the eityof St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Teather ASt-rij'is, of which the 'following is a specification.` y l This .invention relatesto weather-strips, and,.in its most important aspectE pertains more specifcallynto certain new andy useful improvements in weather-strips ofthe slotand-tonguetype adapted to compensate 'for undue shrinkage of the window-sashes and the like to which they are applicable,

Hitherto, this type of strip has consisted of three parts, and one ot the objects of the present invention is to simplityfthis construction softhat but two` parts are necessary. Another object is to Yprovide a vstandard form of strip which is readily applicable to windows and the like of various sizes.

`Another object is to increase the length of,

` and provide irregularities in the path traversed by any leakage of air, and thereby impede and mitigate the flow of air through such path.

Other objects will appear in the course of the following description.

vln the accompanying drawings forming part of this speciiieation, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a horizontal sectional view on the irregular line 1-1 oi? Figure 2, ot a window-frame and sash to which the .veather-strip of this invention has been ap plied; and

Figure 2 is a fragmentary vertical sectional view taken on the irregular line 2-2 et Figure 1.

A winden-*frame 1 has the conventional parting bead 2 between the inner sash runway 3 and the outer sash runway 4, and, also, has the inside bead 5 for confining the sash 6 within proper bounds. The windowsash 6 is of the usual type and contains the Iglass pane 7 secured to the sash 6 by the bead 8.

In equipping a window with this invention, the part-ing bead 2 is removed, and a slot 9 is formed in its inner side 10, for the reception of one end of the weatheretrip l1.

i slot 9.

The inside bead 5 is removed for the purpose of planing a recess 12 on the inner half ot its rear to provide a seat for the other end or edge of the strip 11. The windowsash is next removed and the bead 2 replaced in the trame and strip 11l inserted in The strip 11 may be of any suit-able material, and consists ot a web portion 1S having its tree edge 1e inserted in the recess 12 and terminating at its other edge in a half-turn bend 15 abutting against side 1t), and ei" a portion 1G continuing from said bend 15 substantially parallel and oppositely disposed to web 13 in typical channel fashion to term a slot 1T therebetween and bending back upon itself at 18'- and ter minating in end or edge 19 projecting 'slightly beyond the bend 15 into the slot 9.

A deep and narrow longitudinal slot 20 is cut in the narrow or runway side 21 of the sash 6, preferably approximatelyv threeeight-hs of an inch from the outside `tace 22 ,of the sash, and a recess 23 of less depth is made in the sides 21 between the slot 20 and face 22. Another weather-strip 24, of L- shaped cross-section, and preferably ot' metal, has a wide flange 25 and a narrow flange 2G. The wide flange or tongue 25 is of such thickness as to make a slidable but suiciently air-tight tit in the slot 20. Flange 25 is provided with transverse slots 27. Flange 25 is inserted .in the slot 29, so that {ia-nge 26 extends outwardly, and pins 28 are driven through the sash G across the slot 2O and through the slots 27. The pins 28 cti-operating with the slots 27 permit lateral movement of the strip 2l, ybut prevent undue longitudinal movement of the said strip in the slot-20. Sash 6 is now replaced in its proper position in the window-trame 1, care being` taken that flange 2G passes between the weblS and the flange 1G oi strip 11. Stop bead 5 is next secured in place in the f 'ame 1 by any suitable fastening means.l the edge or end 14 et strip 11 being clamped and held between the bead 5 and the trame 1.

The usual type of weather-strip 29 may be used at the sill 30 of the frame 1, and iits in the usual slot 31 in the bottom 32 of the window-sash 6. Such a. strip 29 is thinner than the slot 31, except at the end 33, where it makes what is merely a line contact with the sides 34 of the slot 31. On the sides of the window, however, the use of such a strip would result in excessive leakage in the event of undue shrinkage of the sash.

It is manifest that the lateral movement et' the tongue in the slot 2O in the sash G takes care of any undue shrinkage of the window-sash that might occur in use, such slot and tongue construction in itself, however, being contemplated prior to the present invention.

It is further manifest that only one other strip, that is the strip 11, is needed in the present invention to co-opera-te with the strip 24. 1t is obvious that any space existing between iange 26 and web 13 or flange 16, in the event of there being no intimate contact of flange 26 with either web 13 or flange 16, is extremely attenuated because of the narrowness of the slot 17, and, also, relatively long because of the width of the flanges 16 and 26, and both these features of construction, in conjunction with the irregularities, such as the bends 15 and 18, offer obstruction and impedance to the free ow of air through the said spaces or cracks.

It is, also, to be noted that the strip 11 is universally applicable to beads 2. no matter what variation there may be` between trames of different sizes or makes, in respect to the depth to which bead 2 extends into= the frame 1.

It is, also, obvious that this invention is not necessarily restricted to the use of the strip 24 of L-shaped cross-section, but any suitable strip secured in a suitable manner Lasser 4.

to the sash G and having an edge projecting into the slot 17 may be used in lieu thereof.

Having thus described this invention, we hereby reserve the benefit of all changes in form, arrangement, order, or use ot parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope ot' the following claim.

le claim:

The combination with a window frame having an inside bead-a parting bead provided with a recess extending longitudinally of its inner face but spaced outwardly from the side of the frame-and a sliding sash between the said beads, of a weatherstrip having its inner longitudinal edge seated in the said recess ot the parting bead and its outer longitudinal edge secured between the said inside bead and the adjacent face of the said trame, said weatl'ierstrip having the portion between the said beads lying fiat against the side of the said frame and being provided with a channel-forming bend in the portion adjacent the said parting bead, and a second weatherstrip ot L-sliaped cross-section and uniform thickness having one leg adjustably secured to the said sliding sash and the other leg engaged in the channel of the tirst-men tioned strip.

In testimony whereof we hereunto allix our signatures.
